IMPROVEMENT IN BURNERS FOR COAL-OIL LAMPS.

.To all whom it may concern.-

Be it known that I, JAMES DONNING, of Paterson, in the county of Passaic and State of New Jersey, have invented, made, and applied to use a certain new and useful Improvement in Burners for Goal-Oil and Similar Lamps; and I do hereby declare that the following is a full, clear, and exact description of the said invention, reference-being had to the annexed drawings, making part of this specification, wherein- Figure 1 is a vertical section of said burner, and Fig. 2 is a plan of the same.

The same letters refer to like parts.

Conical deflectors have heretofore been em- 7 ployed at the base of the flame and above the wick. My invention does not relate, broadly, to these devices; but my invention consists in a long wedge-shaped deflectorsetting upon the wick-tube and connected with a deflector rising above the wick and provided with an opening for the flame, and also with perforations for regulating the action of the air in such a manner that a current is supplied at the base of the'flame, and then the flame itself rises from the edges of the slot in the exterior deflector, causing the air from within said deflector to actually enter the flame to supply the oxygen necessary for a perfect combustion, and the two cones set upon the wick-tube, and are removed together when necessary.

In the drawings, a is the burner ring attached to any suitable reservoir.

1) is the screw-cap carrying the wicktube c, and regulating-button and spurs d to raise or lower the wick.

holes, as at 2 2, for admitting air to aid in keeping them cool. The two deflectors can be slipped off the wick-tube in order to trim the lamp, if required.

The air passing in at the lower ends of the deflectors e and f rises, in consequence of the warmth imparted thereto by the parts themselves, and passes against the flame. The air going through the deflector 6 acts directly at the base of the flame, while that from the de flectorfacts on the flame rather higher up, but the currents of air cannot escape until thoroughly impinged upon the flame by the deflector f, and by this means a sufficient amount of oxygen is brought in contact with the flame to produce a complete combustion of the carbonaceous products from the combustion of coal-oil, and thereby a glass chimney can be dispensed with.

My burner, it will be seen, prevents as much as possible the transmission of heat to the screweap and reservoir. At the same time a sufiicient heat exists in the deflectors to pr0- duce the ascending current .of air; and I find that the flame itself appears to rise from the edges of the slot in this deflector 6, showing that air from the inside of the deflector 6 actuall y passes into the flame, and the outlets at the ends of this slot below the wick, and also the holes 2 2, conspire to maintain only the amount of draft required for a perfect con1- bustion, and the parts require to be in about the shape and proportion shown in order to prevent smoking.

WhatI claim, and desire to secure by Letters Patent, is-

Ihe cones e and f, connected to each other and removable together from the wick-tube, and provided with the openings 2 2, to regulate the action of the air on the flame, the parts being proportioned substantially as specified, and for the purposes set forth.

In witness whereof I have hereunto set my signature this 17th day of March, 1862.
